Finally, the main reinforcement 200 of the construction edge member is bound to the composite stirrup 120 by steel wires. Compared with the prior art, the vertical connection structure of the horizontal extension rib and stirrup of the precast concrete wall does not need to use extra stirrups to connect when the vertical connection structure of the horizontal extension rib and stirrup of two adjacent precast concrete walls is connected with the main stirrup 200 of the structural edge member between the two, so that the time for arranging the stirrups in the construction process is saved, the construction difficulty is reduced, the construction efficiency is greatly improved, the use of materials is saved, and the construction cost is reduced.
